Collected documentation of a new life (4)

I believe the answer is:

file

I'm a little stuck... Click here to teach me more about this clue!

'collected documentation' is the definition.
'file' can be an answer for 'documentation' (thesaurus). I'm not certain of the 'collected' bit.

'new life' is the wordplay.
'new' indicates anagramming the letters.
'life' with letters rearranged gives 'FILE'.

'of a' is the link.

Can you help me to learn more?

(Other definitions for file that I've seen before include "Folder; line" , "Tool for sawing through metal" , "Cutting tool or line of people" , "Document folder" , "Line on board" .)

I've seen this clue in the Evening Standard.
